    Abstract:

    [Objective] The effects of sand-prevention along highways were observed to provid theorological basis and pratical experience for sand-prevention system in desert area. [Methods] According to the causes and types of sand-damage in Babusha desert area, cirresponding engineering and biological measurements were carried out to fix the sands. [Results] (1) Regardless of wind speed, the effective defending distance of internetwork of functional solid barriers were far greater than that of the uniform one. And also the reduction of wind speed near the ground before the nets of the functional solid barriers were greater. Though the sand-prevention effect of functional solid barriers behind the nets was a little worse than that of the uniform one, the sand flow was effectively uplifted. Whereby, sand errosion was reduced as a synergistic result of the decrease of sand movement by striking startup and the decrease of net-interwindspeed to the threshold of sand startup. (2) The functional solid barriers have a strcuture with thin upper part and close lower part, this structure can effectively uplift the wind flow, reducing the wind pressure upon the sediment control network and relieving the wind-catching problem. This can solve the erosion problem under the solid barriers. [Conclusion] The two kinds of sediment control networks both have their advantages. The uniform solid barriers can be used to make high upright solid barriers, and the functional solid barriers can be used to make short hidden solid barriers. The two types can both replace traditional materials and have great applicable value.
